The name Gypsywort comes from the belief that Gypsy's were reputed to stain their skin with the juice of the plant, although Howard (1987) states that they used it to dye their linen (Gypsywort in Wikipedia last modified 14:29, 21 May 2007). The alternate common name water-horehound comes from the Old English words har and hune, meaning downy plant. This descriptive name refers to the white hairs that give the related European herb Marrubium vulgare its distinctive hoary appearance. Another suggested derivation is from the name of the Egyptian god of sky and light, Horus. (Horehound in: Encyclopedia of alternative medicine by Claire Hanrahan at FindArticles.com. 15 Nov. 2007).
